RESUMO
Bronchopulmonary sequestration was diagnosed in eight patients, aged 6-47 years during a 13-year period. The sequestration was intralobar in six patients and extralobar in two. Only lower lobes were involved. Recurrent pulmonary infection was the main clinical presentation. Radiographs usually showed an aerated cyst in intralobar sequestration, while extralobar sequestration presented as a homogeneous shadow. Computed tomography of the chest after bolus infusion of contrast medium revealed the anomalous artery in two patients pre-operatively. The main source of arterial supply was the thoracic aorta in both sequestration types, but venous drainage differed between the types. Associated lesions were bronchogenic cyst and extensive bronchiectasis, each in one patient. Surgical treatment was sequestrectomy for extralobar and lobectomy for intralobar sequestration.
